The ratio of hypermethylation CGI distribution in different functional elements of gene. HP, High Prolificacy. LP, Low Prolificacy. The charcoal, blue, orange, gray, yellow, hyacinthine, green, dark blue and brown colors represent distal intergenic, promoter (<=3 kb), 5’UTR, 3’UTR, 1st exon, other exon, 1st intron, other intron and downstream regions (<=3 kb), respectively
